Improvement in axles for children s carriages



UNITED STATES PATENT FFIC HENRY w. WARNER, 0E GREENEIELD, MASSACHUSETTS.

Specification forming part of Letters Patent No. 158,8 l5, dated January19, 1875; application tiled December 11, 1874.

To all whom it may concern:V

Beit known that I, HENRY W. WARNER,

of Greenfield, in 4the county of Franklin and.

State of Massachusetts, have invented certain Improvements in Axles forGhildrens Carriages, of which the following is a specification:

My invention relates to the axles of childrens carriages; and theinvention consists in making the axle of a round rod of metal, andsecurin g the seat-block for the sprin g to the axle by an eyebolt, orequivalent means, so as to dispense with the forming of shoulders on theaxle, and also avoid the necessity of making holes through the axle, ashereinafter more fully described.

Figure I is a side elevation, and Fig. 2 is a cross-section, of aportion of an axle embodying my invention. Figs. 3, 4, and 5v representmodifications of the same.

Formerly, axles for childrens carriages were made of flat or rectangularbars, but laterally they have been made of round rods having Shouldersformed thereon by upsetting and swaging the metal, or by making theshoulders separate and fastening them on the axle; but in all such casesholes were made through the axle and the shoulders to receive bolts forfastening the springs to the axle. It was this weakening of the axle bythese holes that necessitated the forming of shoulders at those points.

In constructing my improved axle, I' take a round rod of metal, A, ofthe proper size, and

provide an eyebolt, C, as represented in Figs. l, 2, and 4, with an eyeof such a size as to permit the axle-rod to pass through it. I provide asmall metallic seat-block, B, upon which the Spring S is to rest, asshown in Fig. 3, the under side of this block B being fitted to rest onthe axle, and having a lhole for the stem of the eyebolt C to passthrough, as shown in Figs. 2 and 3. It will thus be seen that afterSlipping the eyebolt on the axle the seat-block B is slipped on the stemof the bolt, the spring S set thereon, and a nut, e, screwed on the stemof the bolt G, which fastens the whole securely together. Thus I avoidthe making of holes through the axle, and also the forming of shouldersor enlargements on the axle, thereby greatly simplifying and cheapeningthe construction. Instead of using the eyebolt C, a bolt, C', withoutany eye may be used, as represented in Fig. 3, in which case theseat-block will be countersunk, so as to let the head of the bolt ttherein, as shown, and then the Seat-block, with the bolt in it, is tobe soldered or brazed fast to the axle, whereby the same result isaccomplished; or the bolt C may be placed in the mold and the seatbloekB be cast thereon, and then the latter be soldered or brazed to theaxle, as above described. I, however, prefer to use the eyebolt, as itis simpler and stronger. A collar, a, is shrunk or otherwise fastened onthe axle at the inner end of the spindle D, for the hub of the wheel tobear against, and a nut applied at its outer end, in the usual manner.If preferred, however, the collar a and the seat-block B may be cast inone piece, they being connectedby a small strip, c, as shown in Figs. 4and 5, the latter representing the piece detached, and the former showing it applied to the axle. The collar a may be cast directly on the sideof the block B without the connecting part o; but it is customary tomake the body of the carriage somewhat narrower than the space betweenthe wheels, to prevent it from hitting the latter, and to give a neaterappearance, and hence the use of the strip c, whereby, when made in thisway, the seat-block is thrown inward, away from the wheel, the properdistance.

- Although I have shown but one end of the axle, it will, of course, beunderstood that the opposite end is made in the same way, it being aduplicate, and, therefore, not necessary to be shown. It is obvious thatmy improvement may be applied to other carriages, though it is speciallydesigned for childrens carriages.

Having thus'described my invention, what I claim is- The axle forchildrens carriages, consisting of the rod A and the seat-blocks B,secured thereon, whereby the blocks are Secured to the axle withoutmaking holes through the latter, substantially as set forth.
